IMPROVEMENT IN SPlNDLES FQR SPI'NNING-MAHINESa Specification formingpart of Letters Patent No. 172498, dated January 18, 1876; applicationfiled i Match 15, 1875. i

To all whom it may concern:

Be it known that I, DAVID HALL RICE, of Lowell, in the county ofMiddleseX and Commonwealth of Massachnsetts, have invented certainImprovements in Spindles for Spinning-Machines, of which the followingis a specification Thiis` invention relates to that class of spindlescommonly known as dead and live spindles; and consists, first, in theconnection of a fountain-reservoir with the upper hearing of thelive-spindle by means of a passage-way made through the dead-spindlefrom a point below outside lower hearing; and, its object is to insurethe constant lubrication of the upper spindle-bearing, (independently ofthe supply of oil contained, or which passes np between the surfaces ofthe dead and live spindles, when the latter is in rotation,) whereby theoil reaches the upper spindle-bearin g 0011- tinnously in a natural andlimpid state, as hereinafter described.

In the drawings, Figure l represents an elevation of a spindleandbolster with my improvements. Fig. 2 represents a vertical section ofFig. 1. Fig. 3 is a horizontal section of my dead-spind1e, showing theoil-passages.

A is the rail of the spinning-frame. B is the live-spindle. (l is thebolster and oil-cup for the lower spindIe-bearing. This bolster isattached to the rail of the frame by a nut, in the usual way. lnto thisbolster is inserted the dead-spindle, which is formed of two parts: atube or shell, b, and an internal post or standard, 0, which is slippedinto and made to fit closely to the internal bore of the tube b. In thetop of the post c is forned the upper bearing a: of the live-spindle. Onone side a vertical groove, n, is cut in the post c, before it isslipped within the tube, the groove n eX- tending the entire length ofthe post. This groove is thus made to form a passage for the flow of oilwhen the tube and post are slipped or crowded together. The advantagesof thu's forming this passage are, that it is cheaply and easily done,and the combination of the post and tube forms it substantially througha solid steel dead spindle ot' great rigidity, while if the tube Wereused alone it would not be stiff enough to carry the live-spindlesteadly without increasing its size and bearings to render itsapplication to spindles impracti-, At the lower end of the upperspindle-` cable. bearing a; a passage, z, is made through the post c,connecting the groove n with the bearing. The tube b is made to extend'a little higher than the post c, so as to form-a small oil-cup at itsupper end. At the lower end ot' the tube b it is capped with a cover, m,fixed securely to it, and serving to support the post c, which rests thecover m vertically in position withinthetube. Through the center of. thecover m a small hole is bored, and a tube, '0, has one end screwed intothis hole, and is bent around andicarried vertically upward behind therail of the franie, and sustains upon its upper end a fountainreservoir,u, at the same height as the upper end of the dead-spindle. The top ofthe reservoir u extends upward, however, somewhat higher than thedead-spindlc.

It is n'anifest that, the reservoir u being supplied with oil, the upperhearing x of the spindle will be kept lubricated by means of the tube'17, groove a, and passage z, without the oil being exposed to theaction of the rotation of the internal surface of the live-spindlearound the external surface of the dead-spindle, which tends toconsolidate the oil and clog the passage ot' it to the upper hearing.Besides, the action ot' the oil while being lit'ted by the rotation ofthe live-spindle causes frietion between the contiguous surfaces ot' thelive and dead spindles, and requires more power to drive the spindle,all ot' which is avoided by my present improvement.

The fountain-reservoir u may be provided with a cover to exclude dirt,it' desired. The lower spindle-bearing is upon the tube bat the bottomend of the live-spindle, and when the post 0 is fitted to the internalbore of the tube b it is made with what is known as a running fit--thatis, so as to be readily slipped in and out of the tube Without havingany lateral play. It may be itted more or less tightly, but I prefer tofit it as above described.

The efi'ect of this Construction is that the vibration imparted to thetube b by the lower dead-spindle will overflow the Iatter and run downbetween the dead and live spindles into the oil-cup U, where it willlubricate the lower' hearing. The tube 'u is made to screw into thecover or cap m, so as to be attached to the latter after the bolster isinserted into the rail of the spinning-frame, as it would be difficult,and in some cases inpossible, to insert the bolster into 'the rail withthe tube a) and its fountain attached to the bolster. This detachablejoint also enables the spindle to be taken apart and readily cleaned,ii' any of its oil-'passages become clogged. The vertical portion of thetube 'u and its fountain-reservoir u are carried far enough away fromthe liveispindle vertically upward to allow the ring or traverse rail Eof the frame to pass up and down around the bobbin and spindlealongs'ide the fountain and tube v, and in front of them, and thefountain and tube a re behind the rails of the frame, out of the path ofthe traverse, and do not interfere with the operations of spinning anddoflng, while accessible to the spinner' to oil the spindle, which is ofA great'advantage.

What I claim as new and my invention is- 1. The combination of thefountain-reservoir u and its tubula-r extension v, with the upper,spindle-bearing x, and the passage n formed within the dead-spindlefrom a point below the lower spindlebearin g, substantially asdescribed,

2. The combination of the fountain-reservoir u and its tubular extensionu, extending higher than the top of the dead-spindle, with the lowerspindle-bearing and the passage n, and hollow live-spindle B,substantially as described.

3. The combination of the tbuntain-reservoir u and its tubular'extension v, with the pas'- sage n, the two having a detachable joint,substantially asdescribed.

4. The combination of the fountain-reservoir u, placed behind out of'theway of, and along- -side the path of, the traverse or ring rail, and

its tubular extension o, with the spindle, sub-' stantially asdescribed. p 5. The oil-passage n, formed within the deadspindle frombelow the lower spindl'e-bearing to its upper end, substantiallyasdescribed.- DAVID HALL RIGE. Witnesses: p
